This is a new pattern for me by Cottonpod, a UK designer I had not come across before. The pattern uses a V-stitch formed by crocheting in-between two adjacent treble crochet stitches to force them apart, with interspersing rows of tiny diamonds (hence the name).
The original pattern requires a colour change every row, and therefore lots of sewing in of loose ends. I got round this by changing the direction of the coloured rows so that the white V-stitch rows could be crocheted continuously. This made hardly any difference to the pattern visually, but cut down on loose ends by 50%!
Mine is made in the original Cottonpod colours of Drops cotton merino off white (01) jeans blue (16), lavender (23) and ice blue (09) on a 4.5mm hook. It is 80 stitches wide and 32 V-stitch rows long. It measures 65cm x 50cm. I used 40g each of the three colours and 150g of off white.
It was a quick blanket to work up, and I like the colour play possible with the repeating sequence of 3 colours plus cream. If I have a criticism at all it is that the overall fabric has a lot of drape, and I felt it really needed the border to keep it in shape.
